Error description
The SPEC stage in a pipeline may occasionally result in an assert failure 182 due to uninitialized memory. The assert failure produces a series of messages starting with FPLINX409E Assert failure 00000182 at xxxxxxxx FPLINX411I ... In LOADSPAC; offset 00001040 in FPLSPS 06/22/18 11.40 After the dumped register content, a FPLMSG001I is issued pointing to a SPEC stage.
Local fix
Problem summary
**************************************************************** * USERS AFFECTED: All users of programs that use CMS Pipelines * * SPEC stages, including other z/VM components * **************************************************************** * PROBLEM DESCRIPTION: * **************************************************************** * RECOMMENDATION: APPLY PTF * **************************************************************** The SPEC stage failed to initialize a local work area used to hold an intermediate expression result. After processing the item from the specification list, the cleanup code inspected the uninitialized location. This could incorrectly invoke the string cleanup routine that would fail on the integrity check. Even very simple use of the SPEC stage could be impacted.
Problem conclusion
CMS Pipelines has been changed to ensure the local work area is initialized for each specification list item. During development, another defect in the module was corrected that could cause an Assert Failure A5 in routine BUFFERSE in module FPLFRE for a SPEC stage with multiple streams.
